Munich, October 15, 2014 – Munich-based chemical group
WACKER will be presenting its two new silicone impregnants –
WACKER® HC 321 and WACKER® HC 401 – at the 61st SEPAWA
Congress. Both products allow manufacturers to formulate
cleaning agents that lend a remarkably water-repellent surface to
textiles and other substrates. An aqueous silicone emulsion,
WACKER® HC 321 has been developed for these kinds of
household products, primarily as an agent for post-impregnating
textiles. WACKER® HC 401 is a solvent-based impregnant
intended for professional textile laundering. This year’s
SEPAWA Congress runs October 15 – 17 in Fulda, Germany.
Both products are reactive, silicone-based systems. During application, the silicone components adhere to the fibers of the textile
or leather product to form a cohesive, water-repellent film that uniformly envelops individual fibers in a thin layer without sticking
them together.
Both impregnants performed extremely well in standardized tests used for determining resistance to water and dirt – such as
penetration and spray tests. The efficacy of WACKER® HC 321 and WACKER® HC 401 is very close to that of impregnants containing fluorocarbon resins as active agents.
WACKER® HC 321 – Impregnants for Household Applications WACKER® HC 321 is a milky, aqueous silicone emulsion. The
silicone-based actives were selected and formulated to produce a silicone film that remains unaffected by emulsifier inclusions. This
reliably prevents water from reaching the fibers. The impregnant is effective even at room temperature – no heat treatment is required.
The result is a high degree of water repellency that cannot be attained using traditional water-based impregnants. Cotton textiles
treated with WACKER® HC 321, for instance, scored a total of 90 out of 100 index points in the DIN EN 24920 spray test. This means that the water hardly wets the fibers and drips off. The new aqueous emulsion also makes leather, wood and natural stone surfaces
hydrophobic, i.e. water-repellent.
The emulsion can be easily processed to produce ready-to-use, water-based impregnants. The use of WACKER® HC 321 is
especially helpful in spray impregnants used for restoring impregnation in outdoor clothing.
WACKER® HC 401 – Impregnants for Professional Applications WACKER® HC 401 is a solvent-based formulation of silicone actives.
The product is suitable for producing impregnants used in dry cleaning. They are primarily used, however, for restoring previous
impregnation treatments, and are generally sprayed onto the fabric in a textile washing machine.
WACKER® HC 401 exhibits excellent water-repellent properties on cotton. Cotton textiles impregnated with WACKER® HC 401 score a total of 95 points in the DIN EN 24920 spray test. This means that the water hardly wets the fabric. WACKER® HC 401 also repels oil on
leather. As a result, leather jackets impregnated with the product are significantly better protected from unsightly food and grease stains
than untreated jackets.
